The files sizes are high due to the 2048x2048 texture, lower accordingly.
It comes in 4 level of detail meshes-
Bin Low- 304 vertices 308 faces
Bin Medium- 1224 vertices 1224 faces
Wind High- 4896 vertices 4896 faces
The polygons given on the specification box on the right remember are only for the low resolution mesh.
If you want the lower polygon meshes to be more smooth,
you can play around with the 3ds turbosmooth modifier or equivalent. However, this obviously will add polygons.
See the donwloadeable movies for more visual information on the LOD on the meshes.
Comes as 3DS Mesh and Max 8 mesh.
